Airworthiness Directives; Pacific Aerospace Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) AD 2018-
04-09 for Pacific Aerospace Limited Model 750XL airplanes. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by an aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as incorrectly marked and annunciated low oil-
pressure indication warnings. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective September 22, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 22, 
2020.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 by removing AD 2018-04-09, Amendment 39-19205 
(83 FR 9793, March 8, 2018) (AD 2018-04-09) and adding a new AD. AD 
2018-04-09 applied to Pacific Aerospace Limited Model 750XL airplanes 
and was based on MCAI issued by the Civil Aviation Authority (CAA), 
which is the aviation authority for New Zealand. The SNPRM published in 
the Federal Register on June 10, 2019 (84 FR 26775). The FAA preceded 
the SNPRM with a notice of proposed rulemaking (NPRM) that published in 
the Federal Register on October 23, 2018 (83 FR 53409).
    The NPRM proposed to require revising the existing airplane flight 
manual (AFM) (pilot's operating handbook (POH)) with updated 
provisions, clarify that the pressure switch for the low oil pressure 
light may be replaced or modified, and retain the requirement to 
replace the oil pressure/temperature indicator. The NPRM was based on 
the CAA's revision to its previous MCAI, CAA AD DCA/750XL/19A, dated 
April 26, 2018 (referred to after this as ``the MCAI''), to mandate the 
AFM revisions and also to include an option to modify certain oil 
pressure switches. The MCAI states: DCA/750XL/19A revised to introduce 
revision 30 March 2018 for PAL 750XL POH AIR3237, and clarify the AD 
requirements.
    After issuing the NPRM, the FAA discovered an error in the title of 
one of the flight manuals to be revised. The SNPRM proposed to correct 
the error. The FAA is issuing this AD to require new revisions of the 
existing AFM, clarify the requirement to replace or modify the pressure 
switch for the low oil pressure light, and retain the requirement to 
replace a certain oil pressure/temperature indicator.
    You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0842-0002.

Comments

    The FAA gave the public the opportunity to participate in 
developing this AD. The FAA received no comments on the SNPRM or on the 
determination of the cost to the public.

Changes to the AD

    The FAA identified an incorrect Air Transport Association of 
America (ATA) Code of 57 for Wing in paragraph (d), Subject, of the 
SNPRM. The FAA has changed paragraph (d), Subject, of this AD to 
identify the correct ATA Code of 79 for Engine Oil.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting the AD as proposed except for 
the correction to the ATA Code. The FAA has determined that this 
change:
     Is consistent with the proposal in the SNPRM for 
correcting the unsafe condition; and
     Does not add any burden upon the public than was already 
proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pacific Aerospace Temporary Revision Instruction 
Letter, dated October 2017, which includes Pacific Aerospace Temporary 
Revisions XL/POH/00/001, XL/POH/02/001, and XL/POH/03/001; and Pacific 
Aerospace Revision Instruction Letter, dated March 2018, which includes 
Pacific Aerospace POH AIR 3237 Revision, dated March 30, 2018, for 
750XL airplanes. For the applicable configurations, the service 
information includes revisions to the AFM that corrects the incorrect 
instrument markings.
    The FAA also reviewed Pacific Aerospace Mandatory Service Bulletin 
PACSB/XL/088, dated August 11, 2017, which was previously approved for 
incorporation by reference on April 12, 2018 (83 FR 9793, March 8, 
2018), and describes procedures for replacement or modification of the 
low oil-pressure light, pressure switch, and indicator. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, it has 
notified us of the unsafe condition described in the MCAI and service 
information referenced above. The FAA is proposing this AD because the 
agency evaluated all information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    The FAA estimates that this AD will affect 22 products of U.S. 
registry. The FAA also estimates that it would take about 2 work-hours 
per product to comply with the basic requirements of this AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $500 per product.
    Based on these figures, the FAA estimates the cost of this AD on 
U.S. operators to be $14,740, or $670 per product.
    Since this AD requires the same actions as AD 2018-04-09, the costs 
of compliance remain the same and do not impose any additional costs on 
U.S. operators.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
